PRO H50-SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES Functional Description Pro Series (H50) gas fryers contain a welded stainless steel frypot that is directly heated by a high efficiency infrared burner system requiring approximately 43% less energy than conventional burners to cook the same volume.
valve via a normally closed high-limit switch (and, in fryers with built-in filtration systems, a normally closed drain safety switch). Simultaneously, the module causes the ignitor to spark for 4 seconds to light the burner. A flame sensor verifies the burner ignition by measuring the flow of microamps through the flame.

3. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and plug in the electrical cords. Cleaning the Gas Valve Vent Tube 1. Set the fryer power switch and the gas valve to the OFF position. 2.
Page 11
4. On non-CE fryers only, place the gas valve in the ON position. 5. Place the fryer power switch in the ON position. When the burner has lit and burned steadily for at least one minute, compare the gas pressure reading to the pressure for the corresponding gas in the appropriate table below.
7. Place the fryer power switch (and the gas valve in non-CE fryers) in the OFF position. Remove the fitting from the pressure tap hole and reinstall the pressure tap plug. Measuring Flame Current When the burner flame is properly adjusted, it will produce a current between 2.5 µA and 3.5 µA. Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing wire on the ignitor.
1.6.2 Replacing the Temperature Probe or High-Limit Thermostat 1. Disconnect the fryer from the electrical supply. 2. Drain cooking oil below the level of the probe or thermostat. 3. Lift up on the bezel to disengage the tabs on its lower edge from the control panel frame. Swing the controller out from the top and allow it to rest on its hinge tabs.
b. If replacing the high-limit thermostat, use a pin pusher to disconnect the lead running to the connector and insert the corresponding lead from the new thermostat. Disconnect the other lead from the drain safety switch and connect the remaining lead from the new thermostat. 17.
1.6.5 Replacing an Ignitor Assembly DANGER Drain the frypot or remove the handle from the drain valve before proceeding further. 1. Disconnect the fryer from the electrical supply. 2. Disconnect the flame sensor wire by carefully pulling its push-on terminal from the terminal strip on the ignitor.
Page 16
2. Remove the blower motor shield and separate the blower motor from the housing as shown in the illustration on the following page. Remove these screws to remove the shield from the blower assembly. Remove these nuts to separate the blower motor from the housing.
Page 17
6. Light the fryer in accordance with the procedure described in Chapter 3, Section 3.2 of the Pro H50-Series Gas Fryer Installation and Operation Manual (P/N 819-5991). 7. After the burners have been lit for at least 90 seconds, observe the flames through the burner sight glasses located on each side of the combustion air blower.
1.6.7 Replacing a Gas Valve DANGER Drain the frypot or remove the handle from the drain valve before proceeding further. 1. Disconnect the fryer from the electrical and gas supplies. 2. Disconnect the drain safety and high-limit thermostat wires from the gas valve. Mark each wire to facilitate reconnection.
ALL OTHER VALVES 4. Carefully unscrew the valve from the manifold. NOTE: Some models may have the valve attached to the manifold by means of a pipe union. In such cases, remove the valve by uncoupling the union. 5. Remove all fittings from the old gas valve and install them on the replacement valve, using ®...
8. Remove the washers and tubular spacers from the mounting studs, then pull the inner covers straight out toward you until clear of the mounting studs. 9. Grasp the burner firmly and pull it toward you until it clears the burner channels, taking care not to damage the ceramic tiles in the process.
3. Position a container beneath the oil return fitting at the front of the cabinet. Disconnect the flexible oil line from the fitting, allowing any residual oil to drain into the container. 4. At the rear of the fryer, unplug the left connector (as viewed from the rear of the fryer) from the transformer box.
Page 22
DANGER DO NOT attempt to drain more than one full frypot or two split frypots into the SDU at one time. 3. Dismount the topcap by removing the screws on the bottom of each front corner and lifting the topcap straight up. 4.
19. Carefully lift the frypot from the fryer cabinet. 20. Remove the drain valve(s), temperature probe(s), high-limit thermostat(s), and ignitor assemblies. Inspect each of these components carefully and install them in the replacement ® frypot if they are in serviceable condition. Use Loctite PST56765 sealant or equivalent on component threads.
Page 24
9. Remove the rear lower combustion chamber retainers, back, and insulation (9). NOTE: Full-vat units have two-piece backs and four retainers. Dual-vat units have one-piece backs and two retainers. 10. Remove the flue assembly (10). 11. Remove the upper burner rails (11). 12.
Page 26
To re-assemble with new insulation and/or upper burner rails (use illustration on page 1-23): 13. Place the “L” shaped pieces of combustion chamber insulation (1) in the front and rear corners of both upper rail-retaining slots. 14. Use a small amount of furnace or muffler repair cement to seal the gaps at each end of both lower rails.
Page 27
25. Insert the upper front insulation (10) into its retainer (11), making sure that the holes in each piece are aligned with one another. Install the assembly with the insulation side toward the frypot and secure with ¼”-20 washer-nuts. Do not over tighten. 26.
Troubleshooting and Problem Isolation Because it is not feasible to attempt to include in this manual every conceivable problem or trouble condition that might be encountered, this section is intended to provide technicians with a general knowledge of the broad problem categories associated with this equipment, and the probable causes of each.

Verify that the incoming gas pressure (pressure to the gas valve) is in accordance with the appropriate CE or non-CE Standard found in Section 2.3 of the Pro H50-Series Gas Fryer Installation and Operation Manual (part number 819-5991), and that the pressure remains constant throughout all hours of usage.
Page 31
If the fryer’s gas and air supplies are okay, the problem is most likely with one of the electrical components. Examine the ignition module and controller for signs of melting, distortion, and/or discoloration due to excessive heat build-up in the fryer (this condition usually indicates improper flue performance).
325ºF (163ºC) point by pressing the button and entering the code 1652. The test results will be displayed in the computer’s LED panel in minutes and seconds. The maximum acceptable recovery time for Pro H50-Series gas fryers is two minutes and twenty-five seconds.
Cause: Computer is compensating for oil temperature via the sensitivity setting. Corrective Action: Reprogram sensitivity setting for each product. Refer to the appropriate section of the separate Frymaster Fryer Controllers User’s Manual furnished with your fryer for the operating instructions for your specific controller and suggested sensitivity settings.

• Shortening that remained in the pan after previous filtering solidified in the suction tube recess in the bottom of the pan or the suction tube. Adding hot oil to the pan and waiting a few minutes will usually correct this problem. A flexible wire can be used to clean out the suction tube and the recess in the bottom of the pan.
Verifying Solenoid Operation Proper operation of the 24 VAC manifold and Pump Heater Tape pump solenoids can be verified by removing the pump motor lead from terminal 4 of the pump motor relay in the filter wiring box and then activating the oil return lever.

Power light on, heat light cycling, trouble light off, and melt light on: • If fryer oil temperature is below 180ºF (82ºC), the lights indicate the unit is operating normally. • If the oil temperature is above 180ºF (82ºC) and the heat light continues to cycle as if in the melt cycle, this may indicate a defective probe circuit or low incoming 12VAC to the controller.

The following processes will assist you in troubleshooting the 24 VAC circuit and ruling it out as a probable cause: • 24 VAC is not present on the interface board J3 pin 9 (LED 5 (GV)) and, on dual units, on J1 pin 9 (LED 1 (GV)).
